Name four main Homologous series in organic chemistry...... plz hlp me
Akimi4 [234]
I believe the four series you are looking for are straight-chain alkanes, alkenes, and alkynes, and cycloalkanes. These all have the same repeating of CH2 as the base group, while alkenes have a double bond somewhere in the molecule, and alkynes a triple somewhere.

The movement of molecules across a membrane from an area of high concentration to one of low concentration is best described as:
mestny [16]

Answer:

Difussion

Explanation:

Diffusion is the result of a totally random phenomenon in which the molecules of a fluid come and go between two vessels that can be connected by a pipe. These molecules travel in a single direction, where the solute is more concentrated to where it is more diluted.

This movement of particles will be modified according to the length or area of ​​the pipe and the concentration of solute. The greater the difference in solute concentration along the tube, the greater the diffusion

In your own words, define:
vodomira [7]

Hey there!

1.)

The law of conservation of mass states that matter cannot be created or destroyed. This means in a chemical reaction, the products must be equal to the reactants.

2.)

In a balanced chemical equation, there are the same amount of each type of atom, or element, on each side. The products must be equal to the reactants to follow the law of conservation of mass.

3.)

When a chemical reaction occurs, we can see evidence such as bubbles, odor, color change, and heat/light being released. These all are signs that a new substance is being formed.

Hope this helps!
